Nodular cast iron pipe production process information tracking method and system implementing the method

Abstract

The invention discloses a nodular cast iron pipe production process information tracking method and a system implementing the method. According to the method, each production area is respectively provided with a computer terminal and a reader-writer, when a nodular cast iron pipe sequentially enters an annealing zone, a zinc spraying area, a hydraulic press zone, a cement lining zone, a cement health preserving zone, a mouthing brushing area and a package delivering area, the reader-writer of each production area is aligned with an RFID electronic label of the nodular cast iron pipe and reads and records information on the RFID electronic label of the nodular cast iron pipe, the recorded information is transmitted to a switch, the information is further transmitted by the switch to a server, information of the nodular cast iron pipe in a server database is automatically updated by the server, the nodular cast iron pipe of the production area is monitored by the computer terminal in the production area, if the nodular cast iron pipe is qualified, the nodular cast iron pipe enters the next production area, if the nodular cast iron pipe is not qualified, the nodular cast iron pipe is removed from the production area to a waste pipe area, and qualified nodular cast iron pipes finally arrive the package delivering area.

Description

technical field [0001] The invention belongs to the technical field of metal casting, and relates to a method for tracking information in the production process of ductile iron pipes and a system for realizing the method. Background technique [0002] The production process of ductile iron pipe is complicated, and there are many types of equipment. The main equipment is usually provided by more than ten equipment suppliers. Although the individual equipment is closely connected by the front and back processes, they all complete each action independently, and each has an independent PLC and its The upper computer and communication software are usually in various forms and are different from each other. [0003] At present, there is no equipment supplier in the world that can provide a full line of ductile iron pipe production equipment from the annealing furnace area, zinc spraying machine area, hydraulic press area, cement lining area, cement health care area, brush socket a...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a ductile iron pipe production process information tracking method and a system for realizing the method, to solve the problem of manual labeling in the past ductile iron pipe production process, and to realize the tracking of each ductile iron pipe in the ductile iron pipe production. Real-time tracking records of the actual operating position and actual production information from the annealing furnace to the packaging process
